c2 polymers and giant covalent structure

Question 1

What is a polymer?

Answer 1

A polymer is a large molecule made up of repeating structural units called monomers, connected by covalent chemical bonds.

Question 2

True or False: Giant covalent structures are made up of small, discrete molecules.

Answer 2

False: Giant covalent structures consist of a large network of atoms bonded together, not small discrete molecules.

Question 3

Fill in the blank: Polymers can be categorized into two main types: __________ and __________.

Answer 3

addition polymers and condensation polymers.

Question 4

What type of bond is primarily found in giant covalent structures?

Answer 4

Covalent bonds.

Question 5

Which of the following is an example of a giant covalent structure? (A) Water (B) Diamond (C) Sodium chloride

Answer 5

B) Diamond.

Question 6

What property do most polymers have regarding melting points?

Answer 6

Most polymers have low melting points compared to giant covalent structures.

Question 7

Describe one use of polymers in everyday life.

Answer 7

Polymers are used in products like plastic bottles, clothing, and rubber tires.

Question 8

What is the process called when monomers join to form a polymer?

Answer 8

Polymerization.

Question 9

True or False: All polymers are biodegradable.

Answer 9

False: Many polymers are not biodegradable and can persist in the environment.

Question 10

Name one characteristic of giant covalent structures that differentiates them from ionic compounds.

Answer 10

Giant covalent structures have high melting and boiling points due to the strong covalent bonds throughout the structure.
